Description A study on the vegetative propagation of Chinese chaste tree (Vitex
negundo L.) was carried out at the Department of Horticulture, University
of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru
during August, 2010 to December, 2010.
In the present experiment, the effect of growth regulators viz., IBA
and NAA singly and in combinations on rooting of hardwood cuttings was
studied. The treatments comprised of control, IBA at 2000 and 3000
ppm, NAA at 2000 and 3000 ppm, IBA+NAA 2000 ppm each and
IBA+NAA 3000 ppm each and keradix. The experiment was conducted in
a four replicated Factorial Completely Randomized Design. Single, double
and triple node hardwood cuttings were treated with the growth regulator
solutions. Observations were recorded on various shoot and root
parameters and the survival percentage of rooted cuttings was also
studied. The shoot parameters such as days taken to sprout, number of
sprouts, length of longest sprout and fresh and dry weights of sprouts (9
days, 3.23, 20.38 cm, 3.6 g and 0.88 g, respectively) and the root
parameters like time taken to root, number of roots, length of longest
root, fresh and dry weights of roots were significantly higher (30 days,
19.05, 21.75 cm, 2.37 g and 0.67 g, respectively) in three node stem
cuttings treated with IBA 3000 ppm. The results of this investigation
clearly brought out that, triple node hardwood cuttings should be treated
with 3000 ppm IBA to obtain maximum rooting success and also for
obtaining maximum survival of rooted cuttings in secondary nursery.
